Co-first authors: Ling-Hong Zhu and Zhao-Xin Jin.
Co-corresponding authors: Yong-Mei Lan and Zi-Long Zhang.
Author contributions: Zhu LH and Jin ZX, as co-first authors, made equal contributions to this work. The designation of Zhu LH and Jin ZX as co-first authors serve three key purposes. First, this collaborative research project accurately reflects the division of responsibilities and workload during its completion and paper writing. This arrangement ensures effective communication and post-submission management, ultimately enhancing the quality and reliability of the research. Second, the research team comprises authors from diverse disciplines with specialized expertise, and the co-first authorship best demonstrates this diversity. This structure facilitates comprehensive and in-depth exploration of the research topic, enriching readers 'understanding through multiple expert perspectives. Third, both researchers contributed equally throughout the research process. By selecting these scholars as co-first authors, we acknowledge their equal contributions while recognizing the team's collaborative spirit. In conclusion, we consider the designation of Zhu LH and Jin ZX as co-first authors appropriate, as it accurately reflects our team's collaborative ethos, balanced contributions, and diversity. Lan YM and Zhang ZL contribute equally to this study as co-corresponding authors. They made critical revisions to the important intellectual content of the manuscript, and played a role in designing the work, preparing, validating and supervising the manuscript, and participating in the revision process. Zhu LH, Jin ZX, Ma YQ, Feng X, Ci CH, Zhou YS, Gu QL, Lan YM, and Zhang ZL were responsible for research design; Ma YQ, Feng X, and Ci CH conducted laboratory testing and clinical data collection; Zhou YS and Gu QL performed tool analysis; Zhu LH and Jin ZX handled data analysis and co-authored the paper; Lan YM and Zhang ZL provided critical revisions to the manuscript's intellectual content, participated in the work design, manuscript preparation, validation, supervision, and revision processes; all authors have reviewed and approved the final version.
